Application filed August 11, 1925. 'Serial No. 49,620.

My said invention relates to a turnstile which finds its most importantuse in selfserving stores of the Piggly Wiggly type but may obviously beused in other situations either. in" the form hereinafter described orin other forms. It is an object of the invention to provide "a device ofthis character 1: locking means shall be concealed. 1

Another objectlof the invention is to. pro-' vide a device of thischaracter in which the various connecting parts, etc. shall beconcealedso as to presentsubstantially a plain" smooth: surface of wood or othermaterial to the observer. v v 7 Referring to the accompanying drawingswhich are made apart hereof and on which similar reference charactersindicate similar parts, Figure 1 is a planof my device; Figure 2, avertical section partly'in elevation, V 3

Figure 3, a horizontal section through the locking means, and a Figure4, a detail of the locking means with the concealing parts omitted.

In the drawings reference character 10 indicates 'a post, the top onlybeing shown.

7 At oneside the block has slots 141- formed therein theseslotsextending circumferentially of the block for a limited distancefandgrowing shallower toward their outer ends as clearly shown in Fig. 3. Inthe present embodiment of the" invention balls 15 are shown in theslotsgthes'e balls being forced toward'the ends of the slots by means ofcoil springs 16 bearing at one end against the balls and at the otherbeing formed to clasp pins 17 which are secured in any suitable manner.to the block 12. As here shown the slots 14 are ofsufii'cient'length toperwit the springs to be turned in either direcs'ecure by LettersPatent, is:

The operation of the device is believed to' be obvious from theabovedescription in con: nection With-the drawings.
